They are CNN Heroes, each of whom shows how one person can truly make a difference.

Again this year, CNN encourages you to tell us about these everyday people changing the world -- by nominating them at CNNHeroes.com. Taking a few minutes to share their story with us could propel them to worldwide recognition.

Maybe someone's selflessness has directly impacted your life.

Destiny Bush nominated her mentor and "second mother," Tawanda Jones, whose drill team provides discipline and inspiration to thousands of children in the violent city of Camden, New Jersey.

"It was important for the world to see this wonderful individual who commits herself effortlessly -- her heart, her body, her soul -- to our youth," said Bush, now a graduate student.

Or maybe you know an individual in your community whose personal story and dedication inspires you.

Denada Jackson's mom used to style Robin Emmons' hair. When Jackson bumped into Emmons years later, she learned about Emmons' efforts to help low-income neighborhoods access healthy, fresh food.

"It just seemed right that I would nominate her, because I've never seen anyone that happy about helping other people," Jackson said. "She's making it happen for others in her community. Just to watch her be honored for that, to get a thank you, that was awesome."

But you don't have to personally know the individual you nominate. Just be familiar with their work.

Johanna Robinette, for example, lives in the same small town as Dale Beatty, who helps build and modify homes for injured veterans. Robinette had heard about Beatty's organization, and she saw nominating him as a way to help draw attention to his efforts.

"To be able to take that time to do that, I was thankful that I did and thankful that (he was) honored in that way," Robinette said. "It felt great to be a part of that."

It's easy to nominate an everyday person changing the world, but a thoughtful, well-written nomination is essential to help yours stand out from the thousands we receive. Here are some suggestions we hope will help you in crafting your nomination for consideration.

• Think about what makes your hero special. Ask yourself: What makes my nominee unique? What specific accomplishment has he or she achieved that is truly remarkable? What impact has his or her work had on others? We encourage you to watch videos of previous CNN Heroes to familiarize yourself with the achievements of the inspiring individuals we honor as "everyday people changing the world."

• Take a look at our nomination form. We suggest you review the information requested about yourself, your nominee and his or her work before filling out your submission.

• Tell us about your hero. Take your time and write from the heart. Remember: What you share -- in your own words -- is the most important factor in advancing a nomination for further consideration. You can enter your answers to the essay questions directly on the form, or write them first in a word-processing document and "cut and paste" them into each answer field. Please note the information you provide will be used in accordance with our privacy policy.

• Click "Submit." If your nomination has been successfully transmitted, you'll see a "thank you" message on your screen. If you provided us with your e-mail address, we'll also send a confirmation your nomination has been received. And yes, we read each and every one.

That's it. Nominations for 2014 CNN Heroes remain open through August 31, 2014.
